WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 542,274, dated July 9, 1895.

l Application filed May 26, 1894. Serial No. 512,510. (No model.)

fo all whom t may concern.-

Be it known that I, PETER E.' MoINTosH, a citizen of the United States, residing in Chicago, county of Cook, and State of Illinois,

have invented a new and' useful Spring forwhich- Figure 1 represents a window with a screen having my improved spring attached thereto. Fig. 2 is a plan section of the same, taken on the line 2 2 of Fig. 1, the arrow pointing from the end of the screen which is rst removed from the Window. Fig. 3 is a front elevation --of the springs secured in the groove of the the several views.

screen, a portion of the screen being broken away; and Fig. 4 is a vertical'section of one of the springs, made on line 4 4 of Fiff. 3.

Like letters refer to. like parts throughout Referring to the drawings,A is the spring. It `is made of some elastic metal-brass, preferably-to avoid rust. It is bent slightly at one end and has two screwfholes Vthrough the short part thus bent. At the other end it is bent at right angles in tlleopposite direcand its head is made so .large that the latter will not pass through the. socket. 'The wire is not bent to lform a screw-hole at the other end until after it has been passed through the socket. The catch and spring are screwed to the screen in its groove with the right angle ot' the spring outward and the head inward.

Being thus secured the spring is ready for` use. I thus make the spring in two parts joined together by the socket and head combination, as shown, so that when the screen J is not in use upon a window it will not be possible to pull the spring out of the groove, as could be done if the spring were made in the usual way-that is, so as to be secured to the inner surface of the groove at only one end and curved outward to the edge of the groove. v

The application of the screen to `the window when -iitted with my spring is obvious. One of the grooves having been fitted with two of thel springs, this groove is applied to the strip D, secured on the window-frame E, and pressed toward the strip until the spring, yielding, allows the other groove to be passed over the corresponding strip on the other side of the Window-frame, and the hand letting the screen go the spring forces it into its proper place in the front of the window F.

Having fully described my invention, what I claim, and desire to secure by Letters Patent of the United States-is- The combination of the window screen, C,

formed with the grooves, c, in its edges; the

strips, D, secured on the opposite inner sides of a Window frame; with a spring made of elastic metal bent at right angles at lone end, and having a socket through such bent part, and at the other end slightly bent in the opposite direction, and having two screw holes through it in such bent portion; and a wire catch, formed with a head too large to pass through the socket, and at the other end having a screw hole, the catch passing through the socket in the 'head of the former, the spring and catch being screwed to the screen in its groove; substantially as and for the purpose specified. n
